He's one of the most divisive figures in world football, but there's no question of how popular Diego Costa is in west London.
The burly striker made has name at Chelsea due to his ruthless and aggressive style of play which served the Blues so well for three years.
Costa's trademark approach was his ability to be prolific in front of goal while simultaneously winding up opposition defenders and tricking them into giving away needless fouls and picking up bookings and sendings off.
He was renowned for playing his game on the edge, and fans saw exactly that during Atletico Madrid's stunning pre-season clash with arch rivals Real Madrid, which saw Atletico win 7-3.
Costa started the clash alongside former Chelsea star Alvaro Morata, and scored four goals against Zinedine Zidane's side before being sent off for an angry altercation with Dani Carvajal.
It was a game that summed up the former Chelsea star perfectly, and supporters from around Stamford Bridge couldn't hide their nostalgia as they urged the Blues to bring the striker back to west London.
Here's what fans were saying on social media.
